1.crm
客户关系管理系统 :1.业务逻辑部分 2.权限插件
2.forms组件之modelform
modelform就是model+form ，form根据model的字段生成标签 ，校验信息以及记录的功能 ,一步提交所有数据功能
使用方法：
1)定义个类继承forms.modelform
2)定义哪些字段生成标签fields = ‘__all__‘所有标签
3)定义错误信息以字典的格式
4)重写init方法使用插件给标签更新属性
5)实例化modelform时候 ,如果是对已有对象进行修改需要添加 instance = 已有对象这个参数 ,指定修改对象生成前段标签
6)is_valid()通过后可以直接使用 obj.save()提交数据
####model class Dep(models.Model): name = models.CharField(max_length=32, verbose_name=‘部门‘) #前端的显示label等于verbose_name desc = models.CharField(max_length=128, verbose_name=‘描述‘) ####view from django import forms # Create your views here. class DepForm(forms.ModelForm): # 也可以重写modle中已有的字段！ # name = forms.CharField() class Meta: model = models.Dep fields = ‘__all__‘
#exclude = [] #排除字段
error_messages = { #给每个字段定义错误提示 ‘name‘:{ ‘required‘: ‘必填项‘ }, ‘desc‘:{ ‘required‘: ‘必填项‘ } } def __init__(self, *args, **kwargs): #定义字段生成标签的属性！ super(DepForm, self).__init__(*args, **kwargs) for field in self.fields.values(): field.widget.attrs.update({‘class‘: ‘form-control‘}) def depadd(request): form_obj = DepForm() if request.method == ‘POST‘: form_obj = DepForm(request.POST) if form_obj.is_valid(): form_obj.save() return redirect(reverse(‘crm:deplist‘)) print() return render(request, ‘depadd-edit.html‘, {‘form_obj‘: form_obj})
def depedit(request, edit_id):
obj = models.Dep.objects.filter(pk=edit_id).first()
form_obj = DepForm(instance=obj)
if request.method == ‘POST‘:
form_obj = DepForm(request.POST, instance=obj)
if form_obj.is_valid():
form_obj.save()
return redirect(reverse(‘crm:deplist‘))
return render(request, ‘depadd-edit.html‘, {‘form_obj‘: form_obj})
3.优化删除功能使用alter弹窗提示
异步思想: 删除点击后弹出框提示是否删除 ,如果删除前端移除该行记录 ,数据库中删除该条记录 (sweetalter + ajax + 前端js删除父级标签)
4.密码加密处理
用户输入两次密码 ，如果成功 ，直接使用md5加密存放在数据库中 。所以用户输入的密码永远先做md5的处理
url部分
###url from django.conf.urls import url, include from django.contrib import admin from crm.view import user, dep urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^user/list/‘, user.userlist, name=‘userlist‘), url(r‘^user/add/‘, user.useradd, name=‘useradd‘), url(r‘^user/edit/(\d+)/‘, user.useredit, name=‘useredit‘), url(r‘^user/del/(\d+)/‘, user.userdel, name=‘userdel‘), url(r‘^dep/list/‘, dep.deplist, name=‘deplist‘), url(r‘^dep/add/‘, dep.depadd, name=‘depadd‘), url(r‘^dep/edit/(\d+)/‘, dep.depedit, name=‘depedit‘), url(r‘^dep/del/(\d+)/‘, dep.depdel, name=‘depdel‘), ]
